Thanks for an awesome review - now I want one
You're welcome.
There isn't any need to take out those small parts during normal stove operations, is there? (assemble - cook - cool - pack away), is there?
No, there's no reason to take everything into the field unless maybe you were on a long journey across South America or something like that. For a normal camping or backpacking trip of a week or two, set the stove up at home and leave alternate fuel set ups behind.
I wouldn't think those finicky small parts would come into play in the field unless you swap fuel type or have to do intensive field maintenance.
Exactly right.
Speaking of maintenance - what tools do you need for disasembly?
I've started a FAQ on the stove. Check it out:
MSR Whisperlite Universal -- FAQ and Additional Photos Have a look and let me know if I've answered the question.
About those infamous MSR pumps - what's wrong with them? How did they earn their bad reputation?
The current MSR pump, the Duraseal pump, actually isn't bad. It's probably the best design MSR has had since the mid-eighties.
The pumps that MSR had from the mid-eighties through the late 00's (ca. 2008), did have some problems. Most notably:
- The pump tabs that held the shaft to the body would break.
- The valve housing would crack and leak fuel (that would be bad).
- The "O" ring that seals the pump to the fuel bottle would crack and leak.
All of these problems have been rectified to one degree or another on the current generation of MSR pumps. Are MSR pumps as good as something like the pump off of a Soto Muka or Primus Omnifuel? Probably not, but they're decent and certainly more affordable.
